Benefit of a clipping device in use in intestinal bleeding and intestinal leakage.

BACKGROUND: The over-the-scope clip (OTSC) system was first used to close the access route in natural orifice transluminal endoscopic surgery and is increasingly used for other indications. OBJECTIVE: We analyzed the use of the OTSC in intestinal bleeding and in closure of GI tract leaks. DESIGN: Analysis of a consecutive series of patients. SETTING: University hospital. PATIENTS: Nineteen patients (group A: closure of GI leak site, n = 12; group B: complex GI bleeding, n = 7) were retrospectively enrolled in this study. We analyzed outcome and follow-up (6-68 weeks; group A: mean 37 weeks, standard deviation 24) in terms of treatment success (closure of the GI tract leak/durable hemostasis). INTERVENTION: Endoscopic application of OTSCs. MAIN OUTCOME MEASUREMENTS: Resolution of leaks, closure of fistula (group A), or stopping bleeding (group B). RESULTS: In group A, durable closure was achieved in 8 of 12 patients. Sealing a postoperative/postinterventional leak was successful in 6 patients and failed in 3. A gastrocutaneous fistula was primarily closed successfully in 2 patients, but recurred in 1 of these patients. A gastric wall dehiscence in necrotizing pancreatitis was successfully closed in another patient. Group B patients had previous endoscopic treatment failure in 4 of 7 patients (through-the-scope clips, injection of Suprarenin or fibrin glue, others) and were deemed not treatable by through-the-scope clips in 3 of 7 patients. The primary success rate was 100% (7 of 7 patients); durable hemostasis was achieved in 4 of 7 patients, whereas surgery or angiography was necessary in the remaining patients. LIMITATIONS: Retrospective analysis. CONCLUSIONS: Leaks and fistulae are reliably closed with OTSCs in tissue flexible enough to be sucked into the attached cap (eg, in lesions caused <1 week before). GI bleeding may be stopped by OTSCs with reliable transient hemostasis, but durable hemostasis is less frequent.
